“…Recently, characteristic mode analysis (CMA) has been widely employed in antenna design and applications due to its versatility of providing physical insights regarding an antenna’s radiation phenomena 10 , 11 . As a result, CMA has also been used to design and tune UHF RFID tags for different surface environments 12 – 14 . In 14 , a vehicle’s license plate was exploited as a RFID tag using CMA.…”

This paper presents a block-chain enabled inkjet-printed ultrahigh frequency radiofrequency identification (UHF RFID) system for the supply chain management, traceability and authentication of hard to tag bottled consumer products containing fluids such as water, oil, juice, and wine. In this context, we propose a novel low-cost, compact inkjet-printed UHF RFID tag antenna design for liquid bottles, with 2.5 m read range improvement over existing designs along with robust performance on different liquid bottle products. The tag antenna is based on a nested slot-based configuration that achieves good impedance matching around high permittivity surfaces. The tag was designed and optimized using the characteristic mode analysis. Moreover, the proposed RFID tag was commercially tested for tagging and billing of liquid bottle products in a conveyer belt and smart refrigerator for automatic billing applications. With the help of block-chain based product tracking and a mobile application, we demonstrate a real-time, secure and smart supply chain process in which items can be monitored using the proposed RFID technology. We believe the standalone system presented in this paper can be deployed to create smart contracts that benefit both the suppliers and consumers through the development of trust. Furthermore, the proposed system will paves the way towards authentic and contact-less delivery of food, drinks and medicine in recent Corona virus pandemic.

“…Radio frequency identification (RFID) technology is widely used in logistics packaging tracking and supply chain management due to its strong anti-interference ability, long reading distance, and low cost [1,2]. When UHF-RFID tags are directly connected to metallic surfaces such as metallic packaging, automobiles, and containers, they will change the antenna's gain, input impedance, and operating frequency, resulting in problems such as reduced gain and frequency detuning [3]. Hence, a tag placed near the metallic plane induces an image current of the opposite phase in the metallic surface, which dramatically degrades its antenna performance [4].…”

In this paper, a broadband RFID tag antenna based on module matching is proposed, which is suitable for metallic surface. The antenna's 10-dB effective bandwidth covers 820-980 MHz. In order to achieve a more appropriate impedance matching in a wideband, a new technique of module matching to reach a wide frequency band is studied for realizing the consistent change of impedance between the antenna and the chip, and the frequency band is effectively widened. The feasibility of module matching to achieve maximum power transmission is analyzed. Further results demonstrate that the proposed tag antenna provides a stable gain when being mounted on metal plates of various sizes. In addition, the proposed design is cost-effective since it does not require metallic vias and has a compact size. The maximum reading distance at 910 MHz on the metallic surface is 4.5 m.
